Abstract: A radiation system (50), comprising a patient support platform (3). An X-ray radiation source (2a, 2b, 2c) is positioned beneath the patient support platform and enclosed by fixed radiation shielding. An X-ray radiation detector (22) is positioned above the patient support platform. A detector X-ray radiation shield (1, 11) comprising shield extension (7) is arranged on either side of the patient support platform, which extend from the X-ray radiation 5 detector to the fixed radiation shielding. The shield extensions are able to be moved relative to the source radiation shield to allow access to a patient on the support platform.

Abstract: An interventional X-ray system is proposed, the system including a multi X-ray source unit positioned below a patient table. This ‘multiblock’ may comprise several x-ray sources with focal spot positions distributed along the x-y (table) plane. The x-ray sources are operable in a switching scheme in which certain x-ray sources may be activated in parallel and also sequential switching between such groups is intended. The switching may be carried out so that several images with different projection angles can be acquired in parallel. In other words, an optimal multi-beam X-ray exposure is suggested, wherein fast switching in one dimension and simultaneous exposure in the 2nd dimension is applied.

Abstract: A radiation detector for combined detection of low-energy radiation quanta and high-energy radiation quanta, the radiation detector (8) having a multi-layered structure, comprising: a rear scintillator layer (5) configured to emit a burst of scintillation photons responsive to a high-energy radiation quantum being absorbed by the rear scintillator layer (5); a rear photosensor layer (6) attached to a back side of the rear scintillator layer (5), said rear photosensor layer (6) configured to detect scintillation photons generated in the rear scintillator layer (5); a front scintillator layer (3) arranged in front of the rear scintillator layer (5) opposite the rear photosensor layer (6), said front scintillator layer (3) configured to emit a burst of scintillation photons responsive to a low-energy radiation quantumbeing absorbed by the front scintillator layer (3); and a front photosensor layer (2) attached to a front side of the front scintillator layer (3) opposite the rear scintillator layer (5), said front photosensor layer (2) configured to detect scintillation photons generated in the front scintillator layer (3), wherein the high-energy radiation quantum is a gamma ray and the low-energy radiation quantum is an X-ray.
